Here is what they said...
Asha Negi: On sets we have to play holi in continuity as per the requirement of the scene that is written. There are few restrictions which we do not have in real life. Real life doesn't restrict you pouring a bucket full of water on anyone. It depends on our wish about how we want to play it which is not possible in reel life.
Rithvik Dhanjani:In real life you don't have to repeat the same thing again and again and you do not have to wait and pretend to be another character. Just being yourself is what real Holi is all about.
